Split ring resonator antenna adapted for use in wirelessly controlled medical device

Abstract

An infusion pump assembly is disclosed. The infusion pump assembly includes a reservoir for receiving an infusible fluid, a pump assembly for pumping a quantity of infusible fluid from the reservoir to an exit, a first valve assembly configured to selectively isolate the pump assembly from the reservoir, a second valve assembly configured to selectively isolate the exit from the pumping assembly, and a split ring resonator antenna having a resonant frequency comprising a plurality of planar metallic layers.

[0040]In accordance with one aspect of the present invention a system is disclosed. The system includes a split ring resonator antenna having a resonant frequency comprising a plurality of planar metallic layers, at least one control unit, and a transmitting and receiving base unit capable of powering the antenna, wherein the split ring resonator antenna is coupled to the base unit and whereby the antenna wirelessly transmits and receives data from the at least one control unit, whereby the system minimizes the parasitic effects of dielectric materials in close proximity to a wearable radio frequency device.

Problems solved by technology

Many potentially valuable medicines or compounds, including biologicals, are not orally active due to poor absorption, hepatic metabolism or other pharmacokinetic factors.

Additionally, some therapeutic compounds, although they can be orally absorbed, are sometimes required to be administered so often it is difficult for a patient to maintain the desired schedule.

These devices suffer from a number of drawbacks including the malfunction rate.

Reducing the size, weight and cost of these devices is also an ongoing challenge.

Additionally, these devices often apply to the skin and pose the challenge of frequent re-location for application.
